In circular RNA, the 3' and 5' ends normally present in an RNA molecule have been joined together. This feature confers numerous properties to circular RNA, many of which have only recently been identified. Many types of circular RNA arise from otherwise protein-coding genes. Some circular RNA has … grace church sloWebFeb 6, 2015 · Formation of exonic circRNAs In eukaryotic cells the spliceosome acts to remove introns from primary transcripts in a two-step mechanism.
